more just looking to do an engine swap, but may consider the tranny as well if it eliminates possible issues. Are any differences between the auto's rear diff and the manuals rear diff?

Id like to keep the car a manual if possible, but the rear diff is going (binding up on tight turns after highway driving) So if its not possible to use the rer diff off the auto with the manual trasmission ill consider swapping the engine, auto tranny, and rear diff, etc. Does this make sense?

Thanks

an engine only swap is world easier than an engine AND trans swap, plus when going to auto you need the shifter,
all the electronics, and different mounting hardware under the transmission etc...

tbh the motor's should 100% the same if they are dohc

just do a motor swap and fix your rear diff less work and less headaches
